Abstract

Described herein are systems and methods to provide privacy protection and brightness enhancement in an interactive environment. A system may include one or more of a headset, one or more light sources, one or more optical elements, one or more physical processor, and / or other components. A light source may be configured to generate linearly polarized light rays polarized on a first polarization plane along an axis of propagation. A reflective polarizer of an optical element may be configured to transmit light rays polarized on a second polarization plane transverse to the first polarization plane. Light rays polarized along the first polarization plane may be reflected off the reflective polarizer. An absorptive polarizer of an optical element may transmit light rays polarized on the second polarization plane so that light rays polarized along the second polarization plane may be transmitted through both the absorptive polarizer and the reflective polarizer.

Description

FIELD OF THE INVENTION

[0001] The system and methods described herein relate to provide privacy protection and brightness enhancement in an interactive environment, such as an augmented reality environment and / or a virtual reality environment.BACKGROUND OF THE INVENTION

[0002] There are many types of vision systems that provide virtual or augmented reality (AR) displays. In particular, wearable technology such as head mounted displays (HMD) are becoming more popular.SUMMARY

[0003] One or more implementations of a system described herein facilitate providing views of virtual content (e.g., virtual objects in the form of three-dimensional digital imagery) in an interactive environment, such as one or both of a virtual reality environment and / or an augmented reality environment. An augmented reality environment may include views of images of virtual content superimposed over views of a real-world environment. A virtual reality environment may include views of images of virtual content within...
